Threats
Threat protection
A phishing link, a malicious download, a miner hidden in a page: each one starts with a lookup. AdBolish refuses it, for every app on your PC, and a notification tells you what it stopped and which app asked.
Notifications show while the app runs. Blocking doesn't depend on them.

Use cases
When you'll reach for it — Threat protection
Real situations, not a feature list.
- Stop a phishing link in an email before the fake login page loads.
- Block in-browser crypto-miners and crypto scams.
- Find out which program on your PC keeps reaching a malware site.
- Add newly registered domains, a favourite of phishing campaigns, for extra caution.
What it does
Everything Threat protection handles
Built into AdBolish, and on by default where it should be.
Threats
Malware, phishing, scams and command-and-control servers. On by default.
Crypto-mining
In-browser cryptocurrency miners and crypto scams. On by default.
Newly registered domains
Domains registered in the last week. Off by default, and downloads when you turn it on.
Dangerous site blocked
Windows notifies you with the domain and, when Windows says, the app that tried. Click it to open the Threats page.
Just now, with the app
The latest threats blocked since you opened the window, with the app that asked and an Allow menu.
Never a flood
Each domain notifies at most once an hour, and notifications come at most once a minute, with anything in between rolled into the next.
How it works
Using it, step by step
- 1
Nothing to set up
Threats and Crypto-mining are on from the first run, along with the notifications.
- 2
Open Threats to see what was stopped
Dangerous sites stopped lists each site with its category and blocks. Click one to see its domains.
- 3
Follow up on a repeat offender
A program you don't recognise repeatedly contacting malware sites may be unwanted software. Scan your PC with Windows Security.
Under the hood
How it actually works
The lists, and how you hear about them.
- Lists
- Threats, Crypto-mining (on); Newly registered domains (off)
- Notifications
- On by default; at most once a minute, once an hour per domain
- Quiet blocks
- Newly registered domains are blocked without a notification
- Switch
- Notify me when a dangerous site is blocked, on Threats and in Settings
Lists occasionally catch a legitimate site, and newly registered domains can block a brand-new legitimate one. Allow it from the Threats page or Fix a broken site.
